Convert a Gene Construction Kit (GCK) sequence file to EMBL.

What kind of sequence is in your file?

This output needs a sequence type. The selected input format does not record it, so the converter will use your choice.

About this conversion

The converter reads records in the input format and writes them in the output format. Data that the output format cannot store may be lost. The notes under the Convert file button list the important limits for this pair.

Run it with Biopython

For batch work, you can use Biopython's SeqIO.convert function. This output needs a sequence type, so replace the example molecule type with DNA, RNA, or protein to match your file.

from Bio import SeqIO

count = SeqIO.convert("input.gck", "gck",
                      "output.embl", "embl",
                      molecule_type="DNA")
print("Converted %i records" % count)

Sample input file: Gene Construction Kit (GCK)

Gene Construction Kit (GCK) is a binary format, so it cannot be shown as text. Download the sample file to try the converter.

Samples are small illustrative files. Some come from the Biopython test suite (see the project's sample notes); they are not real study data.
